These are great for my garden, not one bird will come in.Love them

When these arrived, each ornament had to be put together. That seemed easy enough. Each mirrored disc is covered on both sides by a sticker that is rather difficult to remove. And, unbeknownst to me, the discs are unbelievably sharp on the edges. As I was trying to pry one of the stickers off, my hand slipped and the mirror sliced through my finger so deeply I probably should have gone to get stitches. I had no idea it was so sharp. So that's the bad news. The good news is that since these have gone up, the birds have not come back in the mornings. So, very effective, but also, somewhat treacherous. Beware.

Excelente, tal y como se describe

The disks appear to be doing the job. Haven't seen bird droppings since I hung them around the porch. Couldn't figure out how to get the adhesive off the disk, but my spouse figured it out and removed the film rather easily. Make sure you read the instructions/follow the illustrations because I kept assembled and then unassembling.

Des palombes cherchaient à construire un nid entre les bonsaï sur mon balcon et m'en ont cassé un, j'ai donc cherché un moyen de les éloigner.Ces "boucles d'oreilles géantes" sont faciles à monter, il faut juste s'aider d'un couteau pour "attaquer" la pellicule plastique et pouvoir l'arracher avec les doigts, l'ensemble du montage a été fait en 20mn.Depuis la mise en place, je n'ai plus revu les palombes et ça a l'avantage de ne pas être un dispositif trop imposant, ni moche.

This worked for like a week. Not worth it.

Works great I do need to replace them with weather damaging them. So at least 1time a year or 2 years replace with new. This has saved many birds lives Everyday I heard a bird hit one of our windows & many times killing them. This has made a huge difference Thank you

Los compre para que los murcielagos no se duerman debajo de la palapa. Son muy ligeros, que ayudan para colgarlos de las vigas. Veamos como funcionan.

Have yet to try. But am hopeful it'll work.

It really worked great last year from keeping the swallows and other nesting birds away from our home (especially up high under eves). This is the 2nd year I bought this as I needed more for other parts of the home and price is reasonable. Only thing I don't care for is that I need to remove the film on both sides of discs (takes time)...but for the money and effectiness is well worth buying. Without it, swallows have made mud nests in the eves of the house and to take that down is enormous amount of time and even with power washer. Unfortunately, if it is "over cast" and sun doesn't get to reflect off the discs for a couple of days consecutively...it is not effective and birds do still make nests under eves. I have fake Owls and Hawk's around for that situation.

They were real effective in keeping the birds away from my awning where they were building nests. I have tried several different things and these work great.

These discs have been up for 2 weeks, and so while I can't say with certainty that they are going to eliminate the problem, i can definitely see how they have great potential to do so!First off, as others have pointed out, these are beautifully crafted discs... excellent quality that should last many years. Assembling the discs is straightforward but easy enough. Be careful with your fingers... the discs can be sharp on the laser cut edges. I assembled all of mine without gloves without a cut, but you want to be careful anyway.I was concerned about putting up anything that would take away from the look of my red saltbox colonial, so I was pleased with how nice these look, and how they don't draw attention to themselves, but just to their actions - confusing I know. What I mean is that the mere presence of these disks doesn't look out of place. Unlike a bird balloon or a decoy owl that clearly looks like "hey - there is a fake owl on that house", these don't stand out by themselves. However, with the slightest breeze and some sunlight they create a light show of spots flying around and draw attention to their movement. Almost like wind chimes. This is why I think they will totally do the job! They are highly effective at causing distraction during the day, when the woodpeckers come out to play!UPDATE: So it's now been 5 months or so since I installed my first set of discs, and I just bought and added a second set. My bird concern has always been about the woodpeckers who seem to live all around me and who last fall made swiss cheese of my trim boards and barn siding. Because I have a seperate barn and an off-angle garage connected to the house by a screen porch, the original 8 sets didn't quite cover the whole house. On the 20x24' barn I hung one set on each corner and that has worked perfectly. On the house I was only able to easily mount one off my electrical electrical wires (which was where most of the damage occured) and the rest i placed in trees near the corners. This actually seemed to work great, as I check the house all of the time for any new pecking. Despite constantly seeing the woodpeckers flying around the property, and hearing them drumming away on nearby trees, there was no new damage to the house - until last weekend I noticed 2 new peck spots on the back of the garage - the one corner of the house where I had no discs in site. I immediately relocated one from a tree and hung it from a spotlight on that side of the garage - and since then no new damage. I figured since these discs have been so effective it was worth buying another set and really loading up the area. I like having them both on the house, and in the smaller ornamental trees I have because I think it helps keep the woodpeckers not only off the house, but also away from it whereas before they would perch in the trees, then fly over to do some drumming and if startled they'd seek refuge in the nearby trees. Now they have a longer flight to get out to the edge of the property to avoid the discs. Considering what they did to my house in the fall (see photo) and how many woodpeckers are still around and drumming, these discs have without a doubt worked!
